Abstract

The utility model relates to a hand brake structure for scooter rear wheels, comprising a scooter frame, a bottom frame, a bottom plate, a front wheel, the rear wheel, a support frame of the rear wheel, a mudguard, a brake handgrip, a brake connecting wire, etc., wherein, the scooter frame is connected to the bottom plate; the tail end of the bottom plate is provided with the support frame of the rear wheel; the mudguard is pivoted on the support frame of the rear wheel; the mudguard is divided into a support shaft section of center positioning, a front end section which is provided with a step hole, and a brake cambered surface section of a tail part; one end of the brake connecting wire is connected with the brake handgrip, the other end penetrates through a conducting wire device of the brake connecting wire, and is inserted and arranged inside the step hole on the bottom of the front end of the mudguard. The front end section of the mudguard is dragged by the brake handgrip and the brake connecting wire so that the rear wheel is braked by the cambered surface of the rear section. The hand brake structure for scooter rear wheels has the advantages of more convenient brake and good safety.

Description

Scooter trailing wheel hand brake structure

The utility model relates to a kind of scooter trailing wheel hand brake structure.

The scooter basic structure of prior art as shown in Figure 1, handle rack 110 links with driver's frame 120, and car body 120 tail ends are provided with a rear wheel support 130, the dashboards 140 that are pivoted in the middle of this rear wheel support 130, trailing wheel 150 is pivoted thereafter.Yet with regard to the foot-operated brake structure of said scooter, when wheel runs into ground relief or slipperiness on roads, make when car body is in service to be rocked, natural reaction according to the people is to land with this body support balance with a pin, and can't in time take the brake measure, therefore strengthened the dangerous coefficient of scooter.

The purpose of this utility model provides a kind of scooter trailing wheel hand brake structure, so that in time take the brake measure when needing, ensures safety.

The utility model adopts following technical scheme for achieving the above object: scooter trailing wheel hand brake structure comprises vehicle frame, base plate, front-wheel, trailing wheel, rear wheel support, dashboard, brake lever and brake line etc., vehicle frame is connected in base plate, the base plate tail end is provided with a rear wheel support, dashboard is pivoted on this rear wheel support, be provided with a flexible member that separates with wheel when making the dashboard normality simultaneously, described dashboard is divided into three segments---and the centre is a location shaft part, front bottom end is provided with stepped hole, and rear is brake cambered surface section; One end of described brake line and brake lever link, and the other end passes brake line wire installation, is inserted in the dashboard front bottom end stepped hole.

The utility model compared with prior art, dashboard is divided into front end rigion and the rear brake cambered surface section that a location shaft part, bottom are provided with stepped hole, front end rigion by brake lever and brake line tractive dashboard causes the back segment cambered surface to check rear wheel, and it is convenient to brake, and security is good.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the schematic diagram of prior art middle slide plate car pedal brake structure;

Fig. 2 is a perspective exploded view of the present utility model;

Fig. 3 is a combination schematic diagram of the present utility model;

Fig. 4 is the exploded enlarged diagram of A among Fig. 2;

Fig. 5 be among Fig. 3 B to partial schematic diagram;

Fig. 6 is an action schematic diagram of the present utility model.

As Fig. 2, Fig. 3, shown in Figure 4, scooter trailing wheel hand brake structure of the present utility model comprises vehicle frame 10, base plate 40, front-wheel, trailing wheel 70, rear wheel support 60, dashboard 50, brake lever 20 and brake line 30 etc., vehicle frame 10 is connected in base plate 40, base plate 40 tail ends connect establishes a rear wheel support 60, on this rear wheel support 60, be pivoted, be provided with a flexible member 502 that separates with wheel when making dashboard 50 normalities simultaneously when mud plate 50; Locating hole 601, the locating hole 504 of dashboard 50, flexible member 502 that one locating shaft, 503 orders are passed rear wheel support 60 cooperate the location.The inner surface of dashboard 50 is provided with the brake cambered surface that cooperates with trailing wheel 70, is provided with several on-slip projections 505 in the cambered surface.Described dashboard 50 is divided into three segments---and the centre is a location shaft part, and front bottom end is provided with stepped hole 501, and rear is brake cambered surface section; One end of brake line 30 and brake lever 20 link, and the other end passes brake line conductor loop 30-1 and brake line wire column 30-2, is inserted in the dashboard 50 front bottom end stepped holes 501.Brake cable conductor loop 30-1 interts the seam place that locks bassoon 101 and T type pipe 102 on vehicle frame 10 by a quick detaching core shaft 103.Brake line wire column 30-2 is fixed in base plate 40 bottoms, and its center is provided with the downward step through hole 30-21 of notch.

The rear wheel support 60 tail ends trailing wheel 70 that is pivoted, with respect to the front end of dashboard 50, its back cooperates with rear wheel support 60 and is provided with braking surface; One end of flexible member 502 is fixed in rear wheel support 60, the other end is resisted against dashboard 50 places.

When in scooter is advanced, needing to brake, need only be when holding handlebar with hand, the brake lever 20 of inwardly holding with a firm grip, because the pulling force of brake lever 20 is delivered to the leading portion of dashboard (that is brake block) 50 then by brake line 30, in the pulling leading portion, be datum mark with stage casing locating shaft 503, cause tail end brake cambered surface to contact and produce friction with trailing wheel 70, trailing wheel 70 is slowed down or stop operating, reach the purpose of brake; Open brake when holding rake 20 when openhanded, dashboard 50 under the bounce effect of flexible member 502, recovery reset condition naturally.
